I use an extension called autoTabDiscard (or something close) that unloads webpages that I didn't access the last 10 minutes, or that doesn't load any tab on startup, but the tabs keep existing in both cases. Then you can setup exceptions as well.

That's an essential for me.

But why open so many tabs when you can just search history or bookmark (in FF you can also tag by double clicking the star icon)

Usually I find everything I needed by time, data, keyword, tag, or bookmark in a few seconds at most by opening history or bookmark by keyboard shortcut.

In my case I think I got used to have specific ff windows for specific stuff, and having the tabs "opened" feels quicker for me. But I guess I could get used to and switch to tags and bookmarking as you said.
